利用teqc软件对JLCORS网络系统的49个连续运行观测站的观测数据质量进行全面的检测与评估,包括数据完整性、电离层延迟及变率、多路径效应等,数据采样率选用30秒,卫星截止高度角为10度。结果显示,95%的观测站采样效率分布在0.9~1之间,80%的观测站CSR值分布在0.0~0.35之间;所有站点多路径MP1、MP2指标的RMS在0.15~0.45m范围内,网络系统内MP1、MP1的最大值分别是SLAN站0.45m和DEFN站0.42m。接收机运行状态良好,观测环境和观测数据质量完全符合《中国地壳运动观测网络技术规程》要求,而且均优于国际IGS站点标准,对于电离层延迟较严重的时段和不健康的卫星进行了统计,可为GNSS后处理提供可靠的依据。

Using TEQC software to comprehensive cheek and evaluate the observation data of 49 continuous operation observation station from JLCORS network system,including data integrity, ionospheric delay and variable rate, multipath effect etc., sampling rate selection for 30 seconds.The results show, 95% of the observation stations sampled effect rate distribution between 0.9~1.80% of the observation stations CSR value distribution between 0.0~0.35; all sites of multipath MP1, MP2 indexes of RMS within 0.15 to 0.45 m range, network system MP1, MP1 maximum value respectively is SLAN station 0.45 m and DEFN 0.42 m station. The receivers are operating in good condition, observation environment and the quality of observation data in full compliance with the the technical specification fo China crustal movement observation network, and are superior to that of international IGS site standards. The statistics data about ionospheric delay time and unhealthy satellite can provide a reliable basis for the treatment of GNSS.
